This modules handles renderpasses allocation and filling. Also handles blitting to viewport framebuffer and render result reading. Changes against the old implementation: - the filling of the renderpasses happens all at once requiring only 1 geometry pass. - The filtering is optimized with weights precomputed on CPU and reuse of neighboor pixels. - Only one accumulation buffer for renderpasses (no ping-pong). - Accumulation happens in one pass for every passes using a single dispatch or fullscreen triangle pass. TAA and history reprojection is not yet implemented. AOVs support is present but with a 16 AOV limit for now. Cryptomatte is not yet implemented.

* A film is a fullscreen buffer (usually at output extent)
|
|
* that will be able to accumulate sample in any distorted camera_type
|
|
* using a pixel filter.
|
|
*
|
|
* Input needs to be jittered so that the filter converges to the right result.
